Congressional ActivityPublic disclosure records show six members of Congress have filed a combined 25 trades in this Health Care sector security between February 2021 and June 2026, with buying activity outpacing selling at 16 purchases against 9 sales. The most-active filers by disclosed trade count are Ro Khanna, Maria Salazar, Rob Bresnahan, and Gil Cisneros, and no bipartisan co-trading clusters are recorded for this name. The disclosure record does not surface any concentrated cross-party trading groupings, reflecting a relatively small and dispersed set of congressional filers. Separately, six executive-branch officials have disclosed eight transactions in the same security across the same general period, representing an overlap in independent public filings.
